I'm running an AWS instance with 4 CPU cores, and I need to monitor the utilization of each core separately. I noticed that the default CPU Utilization metric shows an average for the entire instance, which doesn't give me the detailed information I need. Is there a way to track this per-core usage using AWS monitoring tools like CloudWatch?

You can check out this Stack Overflow thread that discusses monitoring CPU utilization at the core level in AWS. It might have the insights you’re looking for!
If your instance is running Linux and you have terminal access, you can use tools like `top` or `htop`. They give you real-time stats for each core, but for CloudWatch, you might need a different setup to set alarms on specific cores.
I can do it with `top` or `htop`, but I'm looking for a way to set alarms for when one core exceeds a certain threshold. I think CloudWatch would provide better visibility.
